Saul's new favorite activity is banging on things. It doesn't matter what - his exersaucer, the floor, my face, whatever. He discovered that if he held his plastic pacifier in his hand when he hit things, he could make more noise. So we gave him a wooden spoon.
A wonderful time was had and then we narrowly avoided him poking his eye out. Perhaps we should have thought it through a little bit more. Lesson learned.
